What is the difference between the puffing / popping and D.I.C.?Puffing and popping involve a pressure drop towards the atmospheric pressure.
With D.I.C., as the pressure drops towards a vacuum, the product temperature is significantly lower.
A pressure drop towards a vacuum generates an instant cooling that greatly reduces degradation commonly seen with puffing.
D.I.C. gives the opportunity to work on thermolabile products and to achieve the expansion on material with very low glass transition temperature.
